A Study of Pile Fatigue Failures in the Arabian Gulf
The studies outlined the following two topics. First, the motion response of cantilever piles in the ocean. As the piles were not yet supported by the superstructure, they were subjected to additional forces and the freedom to bend in ways that may have caused overstressing at the mudline. The next area of study was the fatigue damage due to cyclic stress associated with motion response. Essentially, the repetitive motions of the waves may produce a cyclic motion in the piles, causing repetitive stress at the same point, namely the mudline in this case.
This report will utilize this situation as a case study to discuss the failure that occurred in the piles and why. An introduction to pile design and the various construction methods will be outlined, as well as an overview of the studies performed and their results.
